CHAPTER II: NEED FOR INVESTMENT

II.1. Investment mission goals

The project "BP Waste Treatment Plant" was built in village 1, Suoi Kiet commune, Tanh Linh district, Binh Thuan province to achieve the following goals:

- Collect, transport, store, process, recycle and destroy domestic, hazardous industrial and medical waste in Binh Thuan province and neighboring districts of Dong Nai in Tanh Linh district in order to contribute strengthen socialization, environmental protection in general and management of hazardous domestic and industrial wastes in particular.

- Promote the development of activities of reuse, recycling and waste destruction that contribute to reducing waste volume, limiting landfilling, saving resources, protecting the environment and people's health for the sake of sustainable development. sustainable development.

- Building a factory to treat domestic and industrial hazardous waste with advanced technology, synchronously ensuring all regulations on environmental protection according to environmental standards/regulations and management system. management according to international standards.

- Create jobs for local workers, increase the budget.

- Help local management agencies have orientation and development in hazardous waste management, raise people's awareness about environmental protection.

II.2. Necessity of investment

The strong process of industrialization and modernization of our country makes the amount of waste continuously increase. According to the Environmental Status Report of the Department of Environmental Protection, the total volume of solid waste emitted by Vietnam in 2010 is about 23 million tons/year. Domestic solid waste accounts for a large volume (80%) of the total solid waste.

Industrial solid waste (approximately 20÷25% of the volume of domestic waste) is 5÷6 million tons/year, of which there is 700,000 tons of hazardous solid waste/year and about 16,000 tons of medical waste/ year. Although the amount of waste is increasingly large and especially serious, the control, management and treatment of waste has not yet responded in a timely manner. In addition, waste treatment technology, especially with hazardous industrial waste, is still outdated, leading to severe environmental consequences, causing negative impacts on human health.

In the past, to treat waste in Vietnam, we often used many methods such as burial, composting and direct burning method (also known as open burning or single-stage burning). However, landfilling is only common for domestic waste and has major limitations such as occupying a large area of ​​land, decomposition time lasting hundreds of years, dispersal of odors and insects, diseases and especially is generating a large amount of leachate which is very toxic to the soil environment as well as groundwater. The method of making microbial fertilizer (compost) from waste can only be done with organic components separated from garbage, but it is very difficult to completely separate them in municipal waste, it requires require equipment and technology that are complex and expensive to implement; the processing time into manure is quite long, so the capacity is difficult to meet the current huge amount of waste; The quality of compost from waste is hardly guaranteed to fertilize crops, especially food crops. With the direct combustion method alone, due to the uncontrolled decomposition and complete oxidation of organic wastes, many toxic gases such as HC, CO... and especially difficult organic compounds are generated. cyclic decomposition of benzene containing chlorine such as the extremely toxic substances Dioxin, Furan. This classic direct incineration method is not allowed in the world and in our country, especially for medical and industrial hazardous waste.

Therefore, to treat domestic waste, BP Environment Company has used electrolysis technology, a technology with many high features; and Lody-50 incinerator for medical waste treatment; At the same time, stemming from the urgent requirement in hazardous waste treatment, the company also applied the FSI-500E generation Hazardous solid waste incinerator method. This is a new technology of Vietnam Furnace, Incineration and Environmental Treatment Joint Stock Company (FBE Vietnam) and its partner is IFZW Industrieofen und Feuerfestbau GmbH from Germany.

This method from German technology has more potential and advantages than other methods such as: thoroughly treating all types of solid and liquid waste; maximum waste volume reduction up to 95%; the processing time takes place quickly right in the Incinerator; can be treated on site or in a planning area not far from the source of waste, reducing costs and risks during transportation; on the other hand, if the residual heat of the exhaust gas can be utilized to generate electricity, generate superheated steam or heat up the drying processes, etc., the economic efficiency of this treatment process will increase.

In addition to modern technology, the construction site of the BP Waste Treatment Plant is our primary concern. Through our analysis, we confirm that Suoi Kiet commune, Tanh Linh district, Binh Thuan province is the optimal location for us to choose to invest.

Finally, with the belief that hazardous domestic, medical and industrial waste will be thoroughly treated, with pride in contributing to a clean green environment for Vietnam in general and the surrounding area. around Tanh Linh district, Binh Thuan province in particular, we believe that investing in the project "BP Waste Treatment Plant" is a necessary and urgent investment in the current period. .

 

CHAPTER III: ANALYSIS OF THE INVESTMENT ENVIRONMENT

III.1. Natural condition

III.1.1. Geographical location

BP waste treatment plant was built in Hamlet 1, Suoi Kiet commune, Tanh Linh district, Binh Thuan province. The boundary of Suoi Kiet commune in the east is adjacent to Han Thanh commune in Ham Thuan Nam district, in the west by Gia Huynh commune, in the south by Tan Minh commune, Tan Nghia commune in Ham Tan district and Tan Lap commune in Ham Thuan Nam district. The North borders Lac Tanh commune.

The coordinates of the land area to build the BP waste treatment plant are as follows:

Milestones	X (m)	Y (m)
1	1215559.00	402357.00
2	1215557.00	402492.00
3	1215476.00	402441.00

The factory area is about 50,000m2 located in Suoi Kiet commune with relatively high terrain of approximately 200m on fairly flat ground, about 500m from DT 720 road.
III.1.2. Topographic

III.1.3. Climate

The climate around the project construction area is transitional between the rainfall regime of the South Central Coast and the Southern Delta. In other words, this is a buffer zone between the heavy rain center of the South (Di Linh Plateau) and the coastal plain.

However, the climate here still changes in two distinct seasons: the rainy season and the dry season. The rainy season is from May to November. The dry season is from October to April of the following year, often with little or no rain, which causes serious water shortages, poor growth and development of trees, and many pests and diseases that greatly affect the environment. crop yield.

The air temperature is high all year round and is relatively stable. Average annual temperature: 22–26°C. The total annual average temperature is 9,300°C.

Average annual humidity is 70-85%. From June to December, the air humidity is 84.3-86.9%. The average humidity of January, February and March is 75.6-76.9%. The highest average annual humidity is about 91.8%. The lowest average humidity is 61.3%. The absolute lowest humidity is below 15% in the dry season.

Monsoon: There are 2 main wind directions: Southwest and Northeast, southwest wind from May to October. Northeast wind (winter wind) from November to April next year, average wind speed 2-3 m/s

III.2. Social and economic conditions

III.2.1. Socio-economic of Suoi Kiet commune

Suoi Kiet has special characteristics, different from other localities in the district. It can be said that, although it is a mountainous commune of a key food district, Suoi Kiet is a commune without land for rice production, in return Suoi Kiet has a rather large area of ​​cash crops and industrial plants.

With such a potential area of ​​land and minerals, Suoi Kiet is also a locality in the district where many businesses come to invest in production and business. Up to now, there are more than 10 businesses operating in the commune.

Suoi Kiet is one of the 08 communes and towns of Tanh Linh district with ethnic minorities. Currently, the commune has 07 ethnic minorities, including ethnic groups: Ra-glai, Cham, Chau Ro, Tay, Thai; Khmer; Muong; The ethnic group with the largest population is the Raglai, with 192 households/826 people. In particular, there is a village of Suoi Sau, located more than 10 km away from the center of the commune, due to free migrants from mainly Dong Thap places to settle down and was established in 2007; It is the only commune of Tanh Linh district that has a railway line, has up to 02 train stations... Take a look at some of these features to see that Suoi Kiet is a place where birds roost, where all the elements converge. of a vibrant population area, rich in diversity of national cultural identity, and also rich in potential for economic, cultural and social development.

III.2.2. Traffic road

The investment area for the construction of a waste treatment plant is far from the main road of DT 720. There are also traffic routes inside Suoi Kiet commune.

III.2.3. Surface drainage system

The drainage system has not been built, currently flows to the sewers around the land.

III.2.4. Dirty drainage system, environmental sanitation

This area does not have a dirty drainage system, all wastewater is drained naturally. The project builds a dirty water drainage system independent of the rainwater drainage system. The sewer system used has a diameter of D200-D300. Garbage is collected and transferred to the center.

III.2.5. Power supply system, public lighting

Currently, the area has a medium voltage line from the national grid, through the 110/220 KV station, it is expected to build more medium voltage line along the national highway and the electricity used for the area will be taken from this line.

III.3. General comments on the current status of the project's investment location

V.2. Domestic waste treatment technology

V.2.1. Selection of waste treatment technology

For domestic waste, the factory will use the technology of pyrolysis (Compact Device for Waste-pro-cessing), a technology with many novelties in terms of technology, design and layout of equipment lines, neat and compact. , sure; linking many types of equipment in a closed tower-shaped space, taking up less space, limiting the spread of pollution; reduce the safe distance so that construction sites can be arranged and installed near waste generation sources, saving transportation costs; high mobility, can be relocated, quickly deal with waste security emergencies at hot times in sensitive areas.

V.2.2. ELECTRICAL THERMAL TECHNOLOGY

- Working principle

Electrothermal technology includes 3 components:

1. Waste collection and collection management with orientation:

There is an organic relationship between the waste source owner and the waste treatment plant, which is reflected in the contract of collection and treatment of domestic waste. Specify the time, place and type of waste to be collected and treated. On that basis, the waste treatment enterprise will arrange labor force, collection means and collection points according to the waste stream (preliminary classification with orientation). Mobilize the means of transport and transfer to the Electrolysis Station for further classification and treatment.

2. Principles of waste sorting technology:

Sorting is a very complex step and plays a decisive role in the entire process of treating mixed waste with many components. Although, oriented collection and transportation, pyrolysis technology applies many principles of classification and reasonable arrangement of equipment lines to achieve the purpose of separating unused components and putting them into combustion. heat. Collect plastic waste, preliminarily process and pack it to sell to recycling facilities. Inert waste is used for leveling or pressure curing to create brick products of all kinds. In particular, the organic waste stream is filtered with less impurities and put into an advanced biodegradation system (hot incubators and electrolytic ripening towers) sterilization and humusification to create clean organic humus products for agriculture...
